More accurate tests in Katabatic to stop whining about bad doglegs. 

* Change: In Katabatic, in AutoSegment::canonize() and
    Session::_canonize() no longer tag Global as WeakGlobal also.
    This avoid to try to make dogleg on them when we shouldn't.
    They where staying WeakGlobal even when there were no longer
    connected to a global.
* Change: In Katabatic, in AutoSegment::makeDogleg(), suppress the
    bug for pad message when we are in the global routing stage.
    At that point it is allowed to make doglegs under the pads are
    they are "layer change" ones.
